Know what your target is, what is in line with it, and what is behind it.

Never shoot at anything you have not positively identified. Remember – in many cases the bullet does not stop with your target and can pass through both interior and exterior walls. In self-defense situations, always be aware of what or who may be behind your target and the assess the risk of hitting an innocent bystander. You may need adjust your line of fire to avoid hitting others. You must assess the deadly threat from your attacker with the deadly threat from your bullets to others. Be keenly aware of your surroundings, whether on the range or in a life threatening altercation. Do not assume anything.
